		Constraint from $\left \| V_{ub} / V_{cb} \right \|$ B hadrons can decay through the $b \rightarrow c$ and $b \rightarrow u$ transitions. The relative ratio of charmless over charmed b-hadron semileptonic decays, is proportional to the square of the ratio : $\left \| \frac{V_{ub}}{V_{cb}} \right \| = \frac{\lambda}{1-\frac{\lambda^2}{2}} \sqrt{\bar{\rho}^2+\bar{\eta}^2}$ This constraint is represented by a circle centered in in the $(\bar{\rho},~\bar{\eta})$ plane. The present experimental information come from inclusive and exclusive measurements (See the Table of inputs).
